Local server for synced online content management system

ABSTRACT

A client device can implement a client-side application for a server-side online content management system. The client-side application can communicate with the server-side online content management system to sync data stored locally on the client-side with data stored on the server-side. A local web server can be implemented on the client device to work in conjunction with the client-side application, such that the local web server can access the data stored locally. The client device can run a web browser that communicates with the local web server. A user of the client device can use the web browser to connect to the local web server to access the synced data stored locally on the client-side. Advantages of accessing the data stored locally using the web browser via the local web server include performance improvements, offline access to the data, and use of native client applications to interact with the data.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.13/849,165, filed Mar. 22, 2013, the contents of the above patentapplication is hereby expressly incorporated by reference in itsentirety for all purposes herein.

TECHNICAL FIELD

The present technology pertains to accessing synchronized data, and morespecifically pertains to reading, accessing, or otherwise interactingwith synchronized data using a local web server.

BACKGROUND

Computing devices and applications are becoming more commonplace. Everyday, people use applications on their computing devices to access andinteract with their data, especially as mobile computing devices andapplications are growing in number and in function. Browsingapplications are frequently used to navigate and access various data.Some people have data that is synced online at servers and locally ontheir devices. A user can store his data at an online server and havethat data synced with local data on his computing device. For example,an email of the user can be stored online and also stored locally on hiscomputing device. When the user deletes the email stored online, thesame local version of the email can be deleted from his computingdevice. Likewise, when the user deletes the local email from his device,the online version of the email can be deleted as well.

In some cases, it can be convenient to use a browsing application tonavigate or interact with data, such as to read the online version ofthe email in the previous example. However, accessing online data viathe browsing application can be slow or unreliable depending on thenetwork connection to the online data. If the network connection isslow, intermittent, or otherwise unreliable, the overall user experienceassociated with using browsing applications to interact with data candecrease.

SUMMARY

Additional features and advantages of the disclosure will be set forthin the description which follows, and in part will be obvious from thedescription, or can be learned by practice of the herein disclosedprinciples. The features and advantages of the disclosure can berealized and obtained by means of the instruments and combinationsparticularly pointed out in the appended claims. These and otherfeatures of the disclosure will become more fully apparent from thefollowing description and appended claims, or can be learned by thepractice of the principles set forth herein.

Disclosed are systems, methods, and non-transitory computer-readablestorage media for a local server operable with a synchronized onlinecontent management system. Various embodiments of the present disclosureenable data to be stored and synchronized at both a local computingdevice and an online content management system.

In some embodiments, a client computing device can implement a clientapplication corresponding to an online content management system. Theclient application can enable selected data (e.g., content items, files,folders, etc.) stored locally on the client computing device to bestored and synchronized at the online content management system. Thesynchronization process between the locally stored data (i.e., localdata) and the data (i.e., online data) stored at the online contentmanagement system can occur at one or more specified times (e.g., at aschedule time, in response to a synchronization command, when data ismodified, etc.).

In one example, the client computing device can be running a webbrowser. In this example, a user of the web browser can use the webbrowser to surf the Internet. During or after surfing, the user candecide to use the web browser to access one or more of his content items(e.g., files) stored at the online content management system. Since thebrowser is already open and being used by the user, it can be moreconvenient to the user to use the browser to access the online data thanit would be to switch to a content navigation (e.g., file navigation)application to access local data (which is synchronized to the onlinedata). However, the user experience associated with accessing onlinedata using the web browser can vary depending on the speed and/orreliability of the network connection (e.g., Internet speed and/oravailability).

The disclosed technology can implement a local server running on theclient computing device. The local server can work in conjunction withthe client application to access and/or interact with the locally storeddata, which is also synchronized with the online data at the contentmanagement system. In some embodiments, the local server can be includedwith the implementation of the client application on the clientcomputing device. Via the local server, a navigation application such asa browser can access and interact with the locally stored data, which issynchronized with the online data. Advantages of locally accessing thesynchronized data via the local server using the navigation applicationinclude (but are not limited to) performance improvements, offlineaccess to the data, and use of native client applications to interactwith the data.

DESCRIPTION

Various embodiments of the disclosure are discussed in detail below.While specific implementations are discussed, it should be understoodthat this is done for illustration purposes only. A person skilled inthe relevant art will recognize that other components and configurationsmay be used without parting from the spirit and scope of the disclosure.

The disclosed technology addresses the need in the art for accessing orinteracting with data that is synchronized with respect to a localcomputing device and an online content management system. The disclosedtechnology can enable a client device to implement a client-sideapplication for a server-side online content management system. Theclient-side application can communicate with the server-side onlinecontent management system to synchronize data stored locally on theclient-side with data stored on the server-side. A local web server canbe implemented on the client device to work in conjunction with theclient-side application, such that the local web server can access thedata stored locally. The client device can run a web browser thatcommunicates with the local web server. A user of the client device canuse the web browser to connect to the local web server to access thesynchronized data stored locally on the client-side. Advantages ofaccessing the data stored locally using the web browser via the localweb server include performance improvements, offline access to the data,and use of native client applications to interact with the data.

An exemplary system configuration 100 is shown in FIG. 1, whereinelectronic devices communicate via a network for purposes of exchangingcontent and other data. The system can be configured for use on a widearea network such as that illustrated in FIG. 1. However, the presentprinciples are applicable to a wide variety of network configurationsthat facilitate the intercommunication of electronic devices. Forexample, each of the components of system 100 in FIG. 1 can beimplemented in a localized or distributed fashion in a network.

In system 100, a user can interact with content management system 106through client devices 102 ₁, 102 ₂, . . . , 102 _(n) (collectively“102”) connected to network 104 by direct and/or indirect communication.Content management system 106 can support connections from a variety ofdifferent client devices, such as desktop computers; mobile computers;mobile communications devices, e.g. mobile phones, smart phones,tablets; smart televisions; set-top boxes; and/or any other networkenabled computing devices. Client devices 102 can be of varying type,capabilities, operating systems, etc. Furthermore, content managementsystem 106 can concurrently accept connections from and interact withmultiple client devices 102.

A user can interact with content management system 106 via a client-sideapplication installed on client device 102 _(i). In some embodiments,the client-side application can include a content management systemspecific component. For example, the component can be a stand-aloneapplication, one or more application plug-ins, and/or a browserextension. However, the user can also interact with content managementsystem 106 via a third-party application, such as a web browser, thatresides on client device 102 _(i) and is configured to communicate withcontent management system 106. In either case, the client-sideapplication can present a user interface (UI) for the user to interactwith content management system 106. For example, the user can interactwith the content management system 106 via a client-side applicationintegrated with the file system or via a webpage displayed using a webbrowser application.

Content management system 106 can make it possible for a user to storecontent, as well as perform a variety of content management tasks, suchas retrieve, modify, browse, and/or share the content. Furthermore,content management system 106 can make it possible for a user to accessthe content from multiple client devices 102. For example, client device102 _(i) can upload content to content management system 106 via network104. The content can later be retrieved from content management system106 using the same client device 102 _(i) or some other client device102 _(j).

To facilitate the various content management services, a user can createan account with content management system 106. The account informationcan be maintained in user account database 150. User account database150 can store profile information for registered users. In some cases,the only personal information in the user profile can be a usernameand/or email address. However, content management system 106 can also beconfigured to accept additional user information.

User account database 150 can also include account managementinformation, such as account type, e.g. free or paid; usage information,e.g. file edit history; maximum storage space authorized; storage spaceused; content storage locations; security settings; personalconfiguration settings; content sharing data; etc. Account managementmodule 124 can be configured to update and/or obtain user accountdetails in user account database 150. The account management module 124can be configured to interact with any number of other modules incontent management system 106.

An account can be used to store content, such as digital data,documents, text files, audio files, video files, etc., from one or moreclient devices 102 authorized on the account. The content can alsoinclude folders of various types with different behaviors, or othermechanisms of grouping content items together. For example, an accountcan include a public folder that is accessible to any user. The publicfolder can be assigned a web-accessible address. A link to theweb-accessible address can be used to access the contents of the publicfolder. In another example, an account can include a photos folder thatis intended for photos and that provides specific attributes and actionstailored for photos; an audio folder that provides the ability to playback audio files and perform other audio related actions; or otherspecial purpose folders. An account can also include shared folders orgroup folders that are linked with and available to multiple useraccounts. The permissions for multiple users may be different for ashared folder.

The content can be stored in content storage 160. Content storage 160can be a storage device, multiple storage devices, or a server.Alternatively, content storage 160 can be a cloud storage provider ornetwork storage accessible via one or more communications networks.Content management system 106 can hide the complexity and details fromclient devices 102 so that client devices 102 do not need to knowexactly where the content items are being stored by content managementsystem 106. In one variation, content management system 106 can storethe content items in the same folder hierarchy as they appear on clientdevice 102 _(i). However, content management system 106 can store thecontent items in its own order, arrangement, or hierarchy. Contentmanagement system 106 can store the content items in a networkaccessible storage (SAN) device, in a redundant array of inexpensivedisks (RAID), etc. Content storage 160 can store content items using oneor more partition types, such as FAT, FAT32, NTFS, EXT2, EXT3, EXT4,ReiserFS, BTRFS, and so forth.

Content storage 160 can also store metadata describing content items,content item types, and the relationship of content items to variousaccounts, folders, or groups. The metadata for a content item can bestored as part of the content item or can be stored separately. In onevariation, each content item stored in content storage 160 can beassigned a system-wide unique identifier.

Content storage 160 can decrease the amount of storage space required byidentifying duplicate content items or duplicate segments of contentitems. Instead of storing multiple copies, content storage 160 can storea single copy and then use a pointer or other mechanism to link theduplicates to the single copy. Similarly, content storage 160 can storefiles more efficiently, as well as provide the ability to undooperations, by using a content item version control that tracks changesto files, different versions of content items (including divergingversion trees), and a change history. The change history can include aset of changes that, when applied to the original content item version,produce the changed content item version.

Content management system 106 can be configured to support automaticsynchronization of content from one or more client devices 102. Thesynchronization can be platform agnostic. That is, the content can besynchronized across multiple client devices 102 of varying type,capabilities, operating systems, etc. For example, client device 102_(i) can include client software, which synchronizes, via asynchronization module 132 at content management system 106, content inclient device 102 _(i)'s file system with the content in an associateduser account. In some cases, the client software can synchronize anychanges to content in a designated folder and its sub-folders, such asnew, deleted, modified, copied, or moved files or folders. The clientsoftware can be a separate software application, can integrate with anexisting content management application in the operating system, or somecombination thereof. In one example of client software that integrateswith an existing content management application, a user can manipulatecontent directly in a local folder, while a background process monitorsthe local folder for changes and synchronizes those changes to contentmanagement system 106. Conversely, the background process can identifycontent that has been updated at content management system 106 andsynchronize those changes to the local folder. The client software canprovide notifications of synchronization operations, and can provideindications of content statuses directly within the content managementapplication. Sometimes client device 102 _(i) may not have a networkconnection available. In this scenario, the client software can monitorthe linked folder for file changes and queue those changes for latersynchronization to content management system 106 when a networkconnection is available. Similarly, a user can manually stop or pausesynchronization with content management system 106.

A user can also view or manipulate content via a web interface generatedand served by user interface module 122. For example, the user cannavigate in a web browser to a web address provided by contentmanagement system 106. Changes or updates to content in the contentstorage 160 made through the web interface, such as uploading a newversion of a content item, can be propagated back to other clientdevices 102 associated with the user's account. For example, multipleclient devices 102, each with their own client software, can beassociated with a single account and content items in the account can besynchronized between each of the multiple client devices 102.

Content management system 106 can include a communications interface 120for interfacing with various client devices 102, and can interact withother content and/or service providers 109 ₁, 109 ₂, . . . , 109 _(n)(collectively “109”) via an Application Programming Interface (API).Certain software applications can access content storage 160 via an APIon behalf of a user. For example, a software package, such as an app ona smartphone or tablet computing device, can programmatically make callsdirectly to content management system 106, when a user providescredentials, to read, write, create, delete, share, or otherwisemanipulate content. Similarly, the API can allow users to access all orpart of content storage 160 through a web site.

Content management system 106 can also include authenticator module 126,which can verify user credentials, security tokens, API calls, specificclient devices, and so forth, to ensure only authorized clients andusers can access content items. Further, content management system 106can include analytics module 134 module that can track and report onaggregate content item operations, user actions, network usage, totalstorage space used, as well as other technology, usage, or businessmetrics. A privacy and/or security policy can prevent unauthorizedaccess to user data stored with content management system 106.

Content management system 106 can include sharing module 130 formanaging sharing content publicly or privately. Sharing content publiclycan include making the content item accessible from any computing devicein network communication with content management system 106. Sharingcontent privately can include linking a content item in content storage160 with two or more user accounts so that each user account has accessto the content item. The sharing can be performed in a platform agnosticmanner. That is, the content can be shared across multiple clientdevices 102 of varying type, capabilities, operating systems, etc. Thecontent can also be shared across varying types of user accounts.

In some embodiments, content management system 106 can be configured tomaintain a content directory identifying the location of each contentitem in content storage 160. The content directory can include a uniquecontent entry for each content item stored in the content storage.

A content entry can include a content path that can be used to identifythe location of the content item in a content management system. Forexample, the content path can include the name of the content item and afolder hierarchy associated with the content item. For example, thecontent path can include a folder or path of folders in which thecontent item is placed as well as the name of the content item. Contentmanagement system 106 can use the content path to present the contentitems in the appropriate folder hierarchy.

A content entry can also include a content pointer that identifies thelocation of the content item in content storage 160. For example, thecontent pointer can include the exact storage address of the contentitem in memory. In some embodiments, the content pointer can point tomultiple locations, each of which contains a portion of the contentitem.

In addition to a content path and content pointer, a content entry canalso include a user account identifier that identifies the user accountthat has access to the content item. In some embodiments, multiple useraccount identifiers can be associated with a single content entryindicating that the content item has shared access by the multiple useraccounts.

To share a content item privately, sharing module 130 can be configuredto add a user account identifier to the content entry associated withthe content item, thus granting the added user account access to thecontent item. Sharing module 130 can also be configured to remove useraccount identifiers from a content entry to restrict a user account'saccess to the content item.

To share content publicly, sharing module 130 can be configured togenerate a custom network address, such as a uniform resource locator(URL), which allows any web browser to access the content in contentmanagement system 106 without any authentication. To accomplish this,sharing module 130 can be configured to include content identificationdata in the generated URL, which can later be used to properly identifyand return the requested content item. For example, sharing module 130can be configured to include the user account identifier and the contentpath in the generated URL. Upon selection of the URL, the contentidentification data included in the URL can be transmitted to contentmanagement system 106 which can use the received content identificationdata to identify the appropriate content entry and return the contentitem associated with the content entry.

In addition to generating the URL, sharing module 130 can also beconfigured to record that a URL to the content item has been created. Insome embodiments, the content entry associated with a content item caninclude a URL flag indicating whether a URL to the content item has beencreated. For example, the URL flag can be a Boolean value initially setto 0 or false to indicate that a URL to the content item has not beencreated. Sharing module 130 can be configured to change the value of theflag to 1 or true after generating a URL to the content item.

In some embodiments, sharing module 130 can also be configured todeactivate a generated URL. For example, each content entry can alsoinclude a URL active flag indicating whether the content should bereturned in response to a request from the generated URL. For example,sharing module 130 can be configured to only return a content itemrequested by a generated link if the URL active flag is set to 1 ortrue. Thus, access to a content item for which a URL has been generatedcan be easily restricted by changing the value of the URL active flag.This allows a user to restrict access to the shared content item withouthaving to move the content item or delete the generated URL. Likewise,sharing module 130 can reactivate the URL by again changing the value ofthe URL active flag to 1 or true. A user can thus easily restore accessto the content item without the need to generate a new URL.

While content management system 106 is presented with specificcomponents, it should be understood by one skilled in the art, that thearchitectural configuration of system 106 is simply one possibleconfiguration and that other configurations with more or less componentsare also possible.

With reference now to FIG. 2, FIG. 2 shows an exemplary systemembodiment for a local web server that is compatible with a synchronizedonline content management system. Exemplary system 200 can includeclient computing device 202 (i.e., client device, client, etc.) and oneor more servers 220 external to client computing device 202. Clientdevice 202 can be running client-side application 204 (i.e., clientapplication). Client device 202 can also be running local web server206. Local web server 206 can be included with or can work inconjunction with client application 204. Moreover, client computingdevice 202 can be running a navigation application, such as acontent/file navigation application or web browser 208.

In some embodiments, client application 204 can be configured tocommunicate with online content management system 222 (e.g., contentmanagement system 106 in FIG. 1) that is running on one or more servers220. Client application 204 can communicate with content managementsystem 222 over a network, such as the Internet. Client application 204can communicate with content management system 222 to sync data storedlocally (i.e., local data) on client device 202 with data (i.e., onlinedata) stored at content management system 222. For example, particularpieces or portions of data stored locally on client 202 can be syncedwith respective pieces or portions of data stored at content managementsystem 222. Accordingly, content items (e.g., files) and/or otherinformation can be stored and synced at both content management system222 and client device 202. In some embodiments, the synchronizationbetween the data stored locally on client 202 and the data stored atcontent management system 222 can occur at one or more specified times,such as at a specified time on a daily basis or at a time specified by asynchronization policy (e.g., whenever a threshold percentage of datahas been modified).

FIG. 3 shows an exemplary system embodiment for a local web server thatis compatible with a synchronized online content management system.Exemplary system embodiment 300 can include client 302 and at least oneserver 320. Client 302 can be running client application 304 and localweb server 306. Client 302 can also be running a navigation application,such as browser 308. One or more servers, such as server 320, can beused to host online content management system 322.

In some embodiments, online content management system 322 can store dataassociated with users or other entities. For example, online contentmanagement system 322 can be configured to include accounts for aplurality of users, each respective account storing data for arespective user (e.g., User A). As shown in FIG. 3, User A's account 330with online content management system 322 can include data such ascontent item X 332 (e.g., file X), content item Y 334, content item Z336, and so forth.

User A can run client-side application 304 that is compatible withonline content management system 322. Client application 304 can beconfigured to communicate 342 with content management system 322. Viacommunication 342, client application 304 can sync local data associatedwith User A's local account 310 and data stored under User A's account330 at content management system 322. For example, local content items(e.g., files) X 312, Y 314, and Z 316 can be synced, respectively, withcontent item X 332, content item Y 334, and content item Z 336 stored atcontent management system 322. In some embodiments, User A's localaccount 310 can be a directory on client device 302. Content items,files, and/or other data placed in the directory for User A's localaccount 310 on client 302 can be synced with data included in User A'saccount 330 on content management system 322.

As shown in FIG. 3, client application 304 can interact with data storedlocally (e.g., content item X 312, content item Y 314, content item Z316, etc.) under User A's account 310. In some embodiments, local webserver 306 can also interact with the data stored locally, such as byinteracting with the local data via client application 304.

Browser 308 can access local web server 306 to interact with the datastored locally (e.g., content item X 312, content item Y 314, contentitem Z 316, etc.). Browser 308 can function as a navigational tool toview, read, browse, or otherwise interact with the local data (e.g.,content item X 312, content item Y 314, content item Z 316, etc.). Asshown in FIG. 3, through communication 346, browser 308 can access localweb server 306 to interact with the local data.

In some embodiments, accessing data (e.g., 332, 334, 336) at contentmanagement system 322 via connection 344 can serve as a back-up oralternative to accessing the local data (e.g., 312, 314, 316) via localweb server 306 and connection 346. Accessing the locally stored data(synced with the data at content management system 322) via local webserver 306 can offer several advantages over using the connection 344(e.g., Internet connection) to access the data at content managementsystem 322. These advantages can include (but are not limited to)improved performance, offline access to data, and the ability to utilizenative applications for interacting with certain data.

FIG. 4 shows an exemplary system embodiment for accessing local datausing a local web server that is compatible with a synchronized onlinecontent management system. Exemplary system embodiment 400 can include aclient 402 and one or more servers, such as server 420. In FIG. 4,client application 404 and local web server 406 can be running on clientdevice 402 and can interact with locally stored data (e.g., 412, 414,416). Browser 408 can also be running on client device 402 and canaccess local web server 406 to interact with the local data (e.g., 412,414, 416) via connection 446. Moreover, client application 404 cancommunicate 442 with content management system 422 to sync the localdata with the data at content management system 422. For example, localcontent items 412, 414, and 416 can be synced, respectively, withcontent items 432, 434, and 436 at content management system 422.

As discussed above, one advantage of accessing synced local data vialocal web server 406 is improved performance. Improved performance caninclude faster interaction and/or operation with the local data. Forexample, the speed of opening content item 414 can be significantlyincreased when content item 414 is opened from browser 408 via local webserver 406 and client application 404, as compared to opening contentitem 434 (synced with content item 414) from browser 408 via webconnection 444. As shown in FIG. 4, content item 414 (as well assynchronized content item 434) can be an image file. Locally openingfull resolution version 418 of image content item 414 via local webserver 406 can be significantly faster than opening image content item434 from online content management system 422. Local connections (e.g.,446) can have significantly less latency issues than other networkconnections (e.g., 442, 444).

In another example, improved performance can include generating previewsfor data. As shown in FIG. 4, content items 412, 414, and 416 can beimage files. As such, thumbnails can be generated for image files 412,414, and 416. The generating and displaying of the previews (e.g.,thumbnails) can be performed more efficiently on client device 202 ascompared to generating previews at online content management system 422and then transmitting the previews from content management system 422 toclient 402 for display. The generating of the thumbnails for local datacan be performed using computing resources of client computing device402.

FIG. 5 shows an exemplary system embodiment for accessing data using alocal web server when a client computing device is unable to communicatewith a synchronized online content management system. In exemplarysystem embodiment 500, client 502 can implement client application 504,local web server 506, and browser 508. Server 520 can host contentmanagement system 522.

As discussed above, another advantage of accessing local data is that auser can still have access to the data when there is no networkconnection (e.g., 542, 544) to content management system 522. In otherwords, accessing data (e.g., 532, 534, 536) stored at content managementsystem 522 can only occur when client 502 can connect to contentmanagement system 522. An advantage of accessing local data is that thedata can still be accessed when the Internet is unavailable or disabled(e.g., 542, 544). In one example, a user can board a plane that does notprovide wireless Internet. During the flight, the user can decide toread a document (e.g., 512 on client 502, 532 on content managementsystem 522). Using browser 508 to access local web server 506, the usercan read the document (e.g., 512 on client 502) even though there is noInternet available during the flight.

In another example (not shown in FIG. 5), the user can be listening to amusic file that is synced on client 502 as file 516 and on contentmanagement system 522 as file 536. If the user plays file 536 on contentmanagement system 522 via browser 508, and if the connection betweenbrowser 508 and content management system 522 is lost 544, then theplaying of file 536 can be interrupted. In contrast, if the user playslocal file 516 on browser 508 via local web server 506, then the playingof file 516 can continue even if there is no connection (e.g., 542, 544)to content management system 522.

FIG. 6 shows an exemplary system embodiment for accessing data using alocal web server to execute an application configured to operate withthe data (i.e., native application). Typically, web applications cannotcommunicate with device operating systems. Accordingly, opening acontent item, such as a file (e.g., 634), at online content managementsystem 622 is typically limited to only using certain web applicationsto open the content item, rather than using native applications to openthe content item. For example, opening image file 634 at contentmanagement system 622 using browser 608 can be limited to executing animage viewer included with or embedded in browser 608 to open image file634.

In exemplary system embodiment 600, local web server 606 and clientapplication 604 are implemented on client device 602 such that local webserver 606 and/or client application 604 can communicate with theoperating system of client 602. It follows that browser 608 can accesslocal web server 606 and/or client application 604 to communicate withthe operating system of client 602. Local web server 606 and/or clientapplication 604 can ask the operating system which applications arenative to a particular piece of data. As such, another advantage oflocally accessing synced data is that the data can be interacted withand/or manipulated using native applications or applications that areconfigured to be operated with the data.

In one example, browser 608 can navigate to image file 614 via local webserver 606. From browser 608, an instruction can be sent via local webserver 606 to select which native application to use to open image 614(e.g., an option to “Open With . . . ” with respect to file 614). Theinstruction can correspond, for example, to a right click of a mousewith respect to an icon representing file 614. Image editor 618 can beincluded among those native applications installed on client 602. Acommand initiated from browser 608 can cause image editor 618 (i.e.,native application, application configured particularly for file 614 orfor a file type associated with file 614) to open file 614. Openingimage file 614 using image editor 618 can provide a richer or otherwisebetter experience than compared to opening image 634 at contentmanagement system 622 with a simpler web image viewer application.

FIG. 7 shows an exemplary system embodiment for securely communicatingamong a local web server, a client computing device, and a synchronizedonline content management system. Communications among local web server706, browser 708, and content management system 722 can correspond, forexample, to hypertext transfer protocol secure (HTTPS) connections(e.g., 742, 744, 746), as shown in exemplary system embodiment 700.However, due to the HTTPS scheme, browser 708 cannot access local webserver 706 by going to target address “https://localhost” because theHTTPS scheme can require a security key, such as a secure sockets layer(SSL) certificate.

In some embodiments, a domain name for online content management system722 can be created, such as“https://www.onlinecontentmanagementsystemlocalhost.com” 718. In orderfor local web server 708 to accept HTTPS connections, there must be apublic key certificate for local web server 708. The certificate must besigned by a trusted certificate authority 730 in order for browser 708to accept the certificate without warning. Certificate authority 730 cancertify or verify that the certificate holder (e.g., domain 718) isindeed the operator of the web server (e.g., local web server 708) thatpresents the certificate.

In FIG. 7, local web server 706 can be set up with SSL certificate 710,which can be prepared, for example, by an administrator of contentmanagement system 722. SSL certificate 710 can be verifiable withcertificate authority 730. In one example, in order to access local webserver 706, browser 708 can go to domain“https://www.onlinecontentmanagementsystemlocalhost.com” 718 (which canalso be prepared or set up by an administrator of content managementsystem 722). Domain name“https://www.onlinecontentmanagementsystemlocalhost.com” 718 can beconfigured to resolve to the loopback Internet protocol (IP) address(e.g., 127.0.0.1), which points back to local web server 706. Browser708 can verify with certificate authority 730 that SSL certificate 710of local web server 706 is valid. Then HTTPS connection 746 can beestablished such that browser 708 can access local web server 706 viadomain name “https://www.onlinecontentmanagementsystemlocalhost.com”718.

In some embodiments, an entry for domain name 718 can be stored in localdomain name service (DNS) 712. This can allow browser 708 to resolvedomain name 718 to the loopback IP address even when there is noInternet connection. In one example, the entry for domain name 718 canbe configured to have a long time to live (TTL) to further ensure orincrease the likelihood that browser 708 will be able to resolve domainname 718 to the loopback IP address.

Furthermore, in some embodiments, client application 704 can include acontent item (e.g., file) that specifies to browser 708 where domain 718resolves to. For example, client application 704 can configured toinclude an ASCII file specifying that domain name 718 resolves to theloopback IP address (e.g., 127.0.0.1), which points back to local webserver 706.

FIG. 8 shows an exemplary method embodiment 800 for using a local webserver that is compatible with a synchronized online content managementsystem. It should be understood that there can be additional, fewer, oralternative steps performed in similar or alternative orders, or inparallel, within the scope of the various embodiments unless otherwisestated. The method embodiment 800 can begin with implementing aclient-side application that communicates with an online contentmanagement system, at step 802. The client-side application can beimplemented on a client computing device. The client-side applicationcan communicate with the content management system to sync data storedlocally on the client computing device with data stored at the onlinecontent management system.

At step 804, the method 800 can run a local web server on the clientcomputing device. The local web server can be configured to communicatewith the client-side application to interact with at least a portion ofthe data stored locally. As mentioned above, the data stored locally canbe synced with the data stored at the online content management system.Step 806 can include running a web browser on the client computingdevice. In some embodiments, any application with web browsingcapabilities can be utilized. In some embodiments, an application withcontent/file navigation capabilities can be utilized.

Then the method 800 can access the local web server running on theclient computing device via the web browser, at step 808. Step 810 caninclude interacting with the at least a portion of the data storedlocally. The interacting with the at least a portion of the data storedlocally can be based, at least in part, on the accessing of the localweb server via the web browser. For example, the web browser can accessthe local web server to open a locally stored content item (e.g., file)significantly more efficiently than it would be for the web browser toopen the synchronized online version of the content item at the onlinecontent management system.

FIG. 9 shows an exemplary method embodiment 900 for using a local webserver that is compatible with a synchronized online content managementsystem. Again, it should be understood that there can be additional,fewer, or alternative steps performed in similar or alternative orders,or in parallel, within the scope of the various embodiments unlessotherwise stated. At step 902, the exemplary method embodiment 900 canrun a client application configured to sync local data on the clientdevice with data on an online content management system. The clientapplication can be run on a client device. At step 904, the exemplarymethod embodiment 900 can run a local server configured to communicatewith the client application to interact with the local data. The localserver can be run on the client device. The local data can be synced, atone or more specified times, with the online data at the online contentmanagement system.

Then the exemplary method 900 can access the local server from theclient device, at step 906. In some embodiments, the local server can beaccessed from a navigation application, such as a browsing application,that is running on the client device. Step 908 can include interactingwith at least a portion of the local data. The interaction can be based,at least in part, on the accessing of the local server from the clientdevice (e.g., from a navigation application running on the clientdevice).

In some embodiments, a request to access or interact with a piece ofsynced data (local data or online data) can be initiated with respect tothe local web server and the online content management systemsimultaneously. The request can be satisfied from whichever sourceresponds first (typically the local web server).

As discussed above, the synchronization of local data and online datacan occur at one or more specified times. In some embodiments, duringtimes of synchronization, the browser can access the online data storedat the online content management system. In one example, the browser canrequest a content item from the client device. The client device caninform the browser that the content item is in the process of beingsynced (e.g., updated). As such, the browser can access the content itemfrom the online content management system.

In some embodiments, various embodiments of the present disclosure canalso enable one or more settings, options, or preferences to be changedvia the browser. For example, the browser can change settings associatedwith a selective sync option for the client application, which specifieswhich content items, files, and/or folders are to be synchronized forthe client device. In another example, the browser can change settingsthat are associated with a unified interface for the client applicationand the online content management system.

In some embodiments, various embodiments of the present disclosure canalso enable the local web server and/or client application to functionas a content delivery network (CDN). In one example, website data (e.g.,HTML files, CSS files, JavaScript files, webpage images, etc.) for theonline content management system can be included with the clientapplication. When the browser accesses the local web server, aninterface similar to the website for the online content managementsystem can be presented in the browser. Moreover, when the browser needsto access the website for the online content management system, thebrowser can load the website much fasters since the website data isstored locally. Additionally, whenever the website data for the onlinecontent management system is changed, the updated website data can beincluded in the client application (e.g., as an update for the clientapplication).

In some embodiments, interactions with the local data via the local webserver can include “read-only” interactions, such as viewing and playingcontent item (e.g., files). In some embodiments, “write” interactionswith respect to the local data, such as sharing content items andmodifying file contents, can be achieved using network connections tothe online content management system. In one example, the clientapplication can only share a file by opening the browser to a link atthe online content management system to share the file. However, inaccordance with the present disclosure, the browser can integrate accessto the online content management system to share the file with theadvantages of locally accessing synced data.

Various embodiments of the present disclosure can also be implementedwith various online services/systems that have client-sidecorrespondences. For example, an online media streaming service can havea client-side application. Media (e.g., music, videos, etc.) storedonline and locally can be synced. Utilizing a local web server to accessthe locally stored media (which can be synced to the online media) canoffer various advantages, similar to the ones discussed above.

It is further contemplated that a person of ordinary skill in the artwould recognize other approaches or variations that can be implementedconsistent with the scope of the present disclosure. For example, insome embodiments, the local web server and/or client application can beimplemented as a web browser extension. In another example, the localweb server and/or client application can enable one or more computingtasks to be performed using computing resources of the client device,thereby reducing resources needed by the online content managementsystem.

An outputdevice 1035 can also be one or more of a number of output mechanismsknown to those of skill in the art. In some instances, multimodalsystems can enable a user to provide multiple types of input tocommunicate with the computing device 1000. The communications interface1040 can generally govern and manage the user input and system output.There is no restriction on operating on any particular hardwarearrangement and therefore the basic features here may easily besubstituted for improved hardware or firmware arrangements as they aredeveloped.

Chipset 1060 can also interface with one or more communicationinterfaces 1090 that can have different physical interfaces. Suchcommunication interfaces can include interfaces for wired and wirelesslocal area networks, for broadband wireless networks, as well aspersonal area networks. Some applications of the methods for generating,displaying, and using the GUI disclosed herein can include receivingordered datasets over the physical interface or be generated by themachine itself by processor 1055 analyzing data stored in storage 1070or 1075. Further, the machine can receive inputs from a user via userinterface components 1085 and execute appropriate functions, such asbrowsing functions by interpreting these inputs using processor 1055.

It can be appreciated that exemplary systems 1000 and 1050 can have morethan one processor 1010 or be part of a group or cluster of computingdevices networked together to provide greater processing capability.
